Haptic feedback for button and scrolling action simulation in touch input devices
First Claim
1. A haptic feedback touch control for inputting signals to a computer and for outputting forces to a user of the touch control, the touch control comprising:
- a touch input device including a touch surface operative to input a position signal to a processor of said computer based on a location on said touch surface which said user contacts; and
at least one actuator coupled to said touch input device, said actuator outputting a force on said touch input device to provide a haptic sensation to said user contacting said touch surface, wherein said actuator outputs said force based on a single-discontinuity waveform.

Abstract
A planar touch control is used to provide input to a computer and haptic feedback is provided thereto. A touch control includes a touch input device with a planar touch surface that inputs a position signal to a processor associated with the computer based on a location of user implemented contact on the touch surface. The computer can position or modify a cursor or image in a displayed graphical environment based at least in part on the position signal, or perform a different function. At least one actuator is also coupled to the touch input device and outputs a force to provide a haptic sensation to the user via the touch surface.

19. A haptic feedback touch control for inputting signals to a computer and for outputting forces to a user of the touch control, the touch control comprising:
-
a touch input device including a touch surface operative to input a position signal to a processor of said computer based on a location on said touch surface which said user contacts, said location being associated with a location of a cursor displayed on a display screen upon which a graphical object is also displayed; and
at least one actuator coupled to said touch input device, said actuator outputting a force on said touch input device to provide a haptic sensation to said user contacting said touch surface, wherein said actuator outputs said force as long as the location of the cursor on the display screen assumes a predetermined relationship with the location of the graphical object on the touch screen. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
